MMA fighter Jon Jones was suspended for a year for violating the UFC's anti-doping policy

The United States Anti-Doping Association handed down a one-year suspension for MMA fighter Jon Jones, after he tested positive for a banned substance before his last scheduled fight against Daniel Cormier.

"Jones’ one-year period of ineligibility began on July 6, 2016, the date of his provisional sanction," USADA officials said in a written statement to FOX Sports. "In addition, Jones has been disqualified from all competitive results obtained on and subsequent to July 6, 2016, including forfeiture of any title, ranking, purse, or other compensation."

Jones argued that he thought he was taking Cialis, a sexual enhancement drug.

The pill wasn't Cialis and he was actually taking a pill produced by the company All American Peptide.

The USADA's report showed that he tested positive for clomiphene and letrozole, which fall under the class of hormone and metabolic modulators.

"On the evidence before the Panel, the Applicant is not a drug cheat," the arbitrators said. "He did not know that the tablet he took contained prohibited substances or that those substances had the capacity to enhance sporting performance."

"However by his imprudent use of what he pungently referred to as a "(expletive) pill" he has not only lost a year of his career but an estimated nine million dollars. This outcome which he admits to be a wake-up call for him should serve as a warning to all others who participate in the same sport."

Jones still has to appear before the Nevada Commission, which could potentially add more time to his suspension, according to FOX News.
